The IRS is now accepting tax returns as the annual tax filing season is underway. The IRS expects taxpayers to file more than 155 million returns this year. Here are some things for taxpayers to consider as they are filing:

People have until Tuesday, April 17, 2018, to file their 2017 returns and pay any taxes due.

Choosing e-file and direct deposit is the fastest and safest way to file an accurate income tax return and receive a refund.

By law, the IRS cannot issue some refunds before mid-February. These refunds are for tax returns that claim the Earned Income Tax Credit or the Additional Child Tax Credit. The IRS expects the earliest refunds related to EITC and ACTC to be available in taxpayer bank accounts or on debit cards starting on Feb. 27, 2018.

Taxpayers should have their year-end statements in hand before filing. This includes Forms W-2 from employers and Forms 1099 from banks and other payers. Doing this helps avoid refund delays and the need to file an amended return.

IRS.gov is the place to go online for tools that help people as they prepare and file their tax return. This includes:

IRS.gov/account allows people to access information about their federal tax account.

Many Individual Taxpayer Identification Numbers expired on Dec. 31, 2017. This includes any ITIN not used on a tax return at least once in the past three years. Also, any ITIN with middle digits of 70, 71, 72 or 80 is now expired. Affected taxpayers should act soon to renew their number.

Some taxpayers may need their Adjusted Gross Income amount from their prior-year tax return. They need this to verify their identity.
